19.4 How to Calculate Standard Cell Potential | General Chemistry

Chad demonstrates how to calculate Standard Cell Potential (a.k.a. emf or voltage) from a Table of Reduction Potentials. He uses both of the commonly used equations and shows the difference between the two and where NOT to make a mistake.
Ecell = Ecathode - Eanode
Ecell = Ereduction + Eoxidation

The Standard Hydrogen Electrode (SHE) is also identified and its importance as a reference electrode is described. Finally, it is demonstrated how to use a Table of Reduction Potentials to identify the strongest oxidizing agent, the strongest reducing agent, and when two species will react spontaneously in a redox reaction.
